based on the equation 5×x+860=2×x+380, you can say
The value of x is -160.
An equation in which the power of any variable is not more than one is called a linear equation.
Here, we are given a linear equation as follows-
5 × x + 860 = 2 × x + 380
⇒ 5x + 860 = 2x + 380
Let us solve the given equation-
Subtracting 2x from both sides, we get
5x - 2x + 860 = 2x - 2x + 380
3x + 860 = 380
Subtracting 860 from both sides-
3x + 860 - 860 = 380 - 860
3x = -480
dividing both sides by 3,
3x/3 = -480/3
x = -160
Thus, the value of x comes out to be -160.

The diamond just asks for numbers that make up a pattern for the two given numbers.
1. Suppose we have two consecutive odd integers. If the smaller one is “x” ; what would we call the large one?
2. We are told there are two consecutive odd integers and the smaller one is 12 more than one third the large one. Use the answer to problem 1 to write a clean equation then find the integers
Main Answer:1) (x + 2)
2) The numbers are 19 and 21.
Concept and definitions should be there:
An odd integer n is an integer which is not a multiple of 2 (or equivalently one more than a multiple of 2). The odd integers are ..., -5, -3, -1, 1, 3, 5, ... Every odd integer can be written in the form 2k + 1 for some unique integer k.
The product of any two odd integers is odd and the result of a division where both the dividend and the divisor are odd is odd. But the sum and difference of any two odd integers are even.
The sum and difference of an even integer and odd integer are odd. Besides 2, all prime numbers are odd. Also, odd integers are really cool
This article is a stub. Help us out by expanding it.
Given data:
1) We have two consecutive odd integers.
Solving part:
Remember that the distance between any two consecutive odd numbers is 2.
5 - 3 = 2
7 - 5 = 2
13 - 11 = 2
etc.
So if the smaller of the two odd numbers is x, then the larger one will be (x + 2).
Given that:
2) We have two consecutive odd numbers, let's write them as:
Solving part:
(2*n + 1) and (2*n + 3)
Where n is an integer number.
We know that the smaller one is 12 more than one third of the larger one, so we have:
(2*n + 1) = 12 + (2*n + 3)/3
Now we can solve this for n
2*n + 1 = 12 + (2/3)*n + 1
2*n - (2/3)*n = 12 + 1 - 1
(4/3)*n = 12
n = (3/4)*12 = 9
n = 9
Then the two consecutive odd integers are:
(2*n + 1) = (2*9 + 1) = 19
(2*n + 3) = (2*9 + 3) = 21
Final Answer:1) (x + 2)
2) The numbers are 19 and 21.

Find the ending
balance:
$2,500 for 25 years at
2.75% annual simple
interest
Show work
Answer:
$4,218.75
Step-by-step explanation:
The formula for computing simple interest I on a principal amount P for t years at an interest rate of R% is given by
I = Prt
The ending balance amount is found by adding the principal to the interest computed
Ending balance = P + I
Here r is the interest rate in % converted to a decimal. This is done by dividing by 100
r = R/100 = 2.75%/100 = 0.0275 per year
I = 2500 x 0.0275 x 25 = 1718.75
So interest I = $1718.75
Ending balance = $2,500 + $1718.75 = $4,218.75

China generated 237.188 billion kilowatt-hours (kWh) of wind energy in 2018. The population in China in 2018 was 1.379 billion. What was the wind energy generated per capita? Give your answer to the nearest hundredth.
Answer:
172 kilowatts.
Step-by-step explanation:
Energy : 237.188 billion = 237,188,000,000 = 2.37188 × 10¹¹
People : 1.379 billion = 1,379,000,000 = 1.379 × 10⁹
Divide both values : 2.37188 ÷ 1.379 = 1.72; 10¹¹ ÷ 10⁹ = 10² ⇒ 1.72 × 10² or 172 kilowatts.

Step-by-step explanation:
The two angles are supplementary angles.
Supplementary angles sum 180°
(6x+4) + 38 = 180
6x + 42 = 180
6x = 180 - 42
6x = 138
x = 138/6
x = 23
Check:
6*23 + 4 + 38 = 180
138 + 42 = 180
Answer:
x = 23Step-by-step explanation:
We know that the sum of angles of a linear pair is always equal to 180°. These angles are also known as supplementary angles.
[tex]\bf 6x+4+38^o=180^o[/tex] (Add numbers)
[tex]\bf 6x+42=180[/tex] (Simplify)

Gabriel is deciding between 2 different movie streaming sites to subscribe to. Plan 1 costs $22 per month plus $1 per movie watched. Plan 2 cost $14 per month plus $3 per movie watched. Create a system of equations to represent this situation. Use the graph below and explain how many movies x would cause the 2 plans would have an equal monthly cost
Using linear functions, it is found that 4 movies would cause the two plans to have an equal monthly cost.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For the functions in this problem, we have that:
The fixed cost is the intercept.The cost per movie is the slope.Hence the cost functions are given as follows:
C1(x) = 22 + x.C2(x) = 14 + 3x.The costs will be the same when:
C1(x) = C2(x).
Hence:
22 + x = 14 + 3x
2x = 8
x = 4.
4 movies would cause the two plans to have an equal monthly cost.

Answer:
True
Step-by-step explanation:
Because you never expect when something may show up once your doing something and forget about what you lost a while back. Sometimes it just pops up and we're like, "Oh that's where it was".
Can't say true or false because both can be answers in different cases, mathematically speaking you can select one thing from a set of similar things having similar chance to be selected. and again you can also select one thing at random from a set of things having different chance of being selected. in my perspective:)
and maybe the question has more chance to be false because if a statement is false at least in one case it is false.
Find an equation for the line which passes through (-2,8) and is perpendicular to the line containing (0,1) and (4,5).
The equation of line which passes through (-2, 8) and perpendicular to the line conatining (0, 1) and (4, 5) is y = -x + 6 .
Let the equation of line passes through the point (-2, 8) be y = mx + b.
Where m is the slope of the line and b is the y intercept of the line.
According to the given question.
A line passes through the points (-2, 8).
And it is also perpendicular to the line containing (0, 1) and (4, 5).
Since, the line is perpendicualr to the line conatining (0, 1) and (4, 5).
So, the slope of the line whose equation is to be find is given by
m = -1/(5 - 1/4-0)
⇒ m = -1/4/4 = -1
Thereofre, the equation of line with slope -1 is
y = -1x + b
Also, it passes through (-2, 8)
So,
8 = -1(-2) + b
⇒ 8 - 2 = b
⇒ b = 6

Calculate a 95% confidence interval for the true difference in population proportions between the people of Washington, DC, and the people of Atlanta who agree with the statement (DC − Atlanta). (Use a table or technology. Round your answers to three decimal places.)
Step-by-step explanation:
Results of the Assembly elections in five States are indeed a shot in the arm for the Bharatiya Janata Party (BJP), which won in all four States where it was in power. The Hindu editorial captures the broad trends that emerge out of these results. Prime Minister Narendra Modi has said these results have sealed the outcome of the 2024 Lok Sabha elections too in the BJP’s favour. He said people have rejected caste and dynastic politics.
b. The number of successes in the Washington sample were 4740 .
The number of failures in the Washington sample is 1,260
c. the 95% confidence interval for the true difference in population proportions between the people of Washington, DC, and the people of Atlanta who agree with the statement "Employers should be required to pay men and women the same salary for the same job" is 0.018 to 0.068.
How do we calculate?(b) Number of successes and failures in the Washington sample:
Total number of respondents in the Washington sample: 6,000
Percentage who agreed with the statement: 79%
Number of successes = 79% of 6,000
= 0.79 * 6,000
= 4,740
Number of failures = Total - Number of successes
= 6,000 - 4,740
= 1,260
(c)
confidence interval = (p1 - p2) ± Z * √((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))
p1 = Proportion of successes in the Washington sample
p2 = Proportion of successes in the Atlanta sample
n1 = Size of the Washington sample
n2 = Size of the Atlanta sample
Z = Z-score for the desired confidence level = 1.96
confidence interval = (0.79 - 0.74) ± 1.96 * √((0.79 * (1 - 0.79) / 6000) + (0.74 * (1 - 0.74) / 4800))
confidence interval = 0.05 ± 1.96 * √((0.79 * 0.21 / 6000) + (0.74 * 0.26 / 4800))
confidence interval = 0.05 ± 1.96 * √(0.00013815 + 0.0001244583)
confidence interval = 0.05 ± 1.96 * √(0.0002626083)
Lower bound of the confidence interval (DC - Atlanta)
= 0.05 - 0.0317226549
